Greenhouse gases: a troposphere story
Solar radiation warms the Earth’s surface. Some of the heat is radiated back to the atmosphere, where it is trapped by greenhouse gases. The most important greenhouse gas is water vapor. Without it, the Earth’s average temperature would be below freezing. With it, the planet is warm enough to support life over most of its surface.
Greenhouse gases include water vapor, carbon dioxide, ozone, methane, and nitrous oxide.
